And that's because cars will continue to be the main mode of transportation in the region.

All the traffic we see every day is one sign that job growth is steady in the region, and authors of this study argue one of the best ways to keep it steady is to keep building to make travel smoother.

But couple that with our love of cars and it will be more of the same.

The new study concludes that because so many commuters favor their cars, and the number of commuters keeps growing, traffic will likely not improve anytime soon.

According to the report, the region is expected to add 1.3 million jobs over the next 30 years.

And while construction of new Metro lines and highway lanes help ease the pain, it's not outpacing the growth.

Alan Pasarki, a transportation consultant on the study, argues more investment is needed in transportation to ensure the new jobs keep coming.

"We're not gonna be back to a perfect day where there's no congestion," Pasarki says."Dependence on the automobile is going to persist."

The study states that over the past 20 years the number of people commuting by car has declined about 3 percent.

But that figure isn't expected to change much in the next several decades.
